This is one of the most iconic quotes of The Joker played by Heath Ledger The Dark Knight, 2008. The Joker is a supervillain and archenemy of Batman, also known as the clown prince of crime, the jester of genocide, the harlequin of hate. He is the most infamous supervillain of all time, a master-mind criminal with a clown-like appearance and menacing smile. The Joker first appeared in Batman #1 and his sole purpose was to wreak as much havoc as possible in Gotham City. In his criminal history, he has shot Barbara Gordon (aka Batgirl) and paralysed her below the waist in The Killing Joke. He has kidnapped Commissioner Gordon and taunted him with images of what he has done to Barbara. He has murdered Jason Todd, the second Robin, in A Death in the Family.

The Joker is manipulative and scheming, making his psychiatrist Harleen Quinzel fall in love with him and driving her over the edge of obsession. She suspects that he is only feigning insanity to avoid the death penalty but becomes sympathetic when he tells her the story of his absent father and abandonment from his mother. She releases him from Arkham Asylum and becomes his closest sidekick, Harley Quinn. Their love affair is revived in 2016 film Suicide Squad, where The Joker is played by Jared Leto and Harley Quinn is played by Margot Robbie. They depicted the creepier version of the nature of their relationship.

With so many variations of The Joker costumes, you can really get creative and display your true insanity. Put on that purple blazer, wear a blonde or green wig, paint that face white and smear lipstick across your face. Couples can wear The Joker and Harley Quinn costumes to stir up some trouble at your next party.
